Coming back fresh made a big difference. I dialed in the horizontal and figured out my problem. This is my first round screen set and I didn't have an idea of what the final picture dimensions should be. I measured the bezel on the cabinet and realized that I had the picture stretched out WAY too far vertically. After I dialed back the vertical size the picture became much more linear. It's still not perfect towards the top of the picture (as you can see by the clock at the top), but it's close enough for me to watch some movies on it and put it back in the back of the restoration cue and move on.

I installed the chassis into the cabinet and now my favorite TV in my collection is a working TV
